Solar System Exit Ticket
| # | Answer |
|---|---|
| 1 | Mercury is the closest planet to the Sun, and Neptune is the farthest planet from the Sun. |
| 2 | Mercury, Venus, Earth, Mars. |
| 3 | Earth is able to support life because it has liquid water, a breathable atmosphere, and temperatures that can allow living things to survive. |
| 4 | No, this is not always true. Planet size can affect the number of moons, but it does not guarantee more moons. For example, Earth is large but has only one moon, while smaller planets like Mars have two moons. |
| 5 | Mars would be one of the more realistic destinations because it has a day length similar to Earth’s and evidence of water ice, but it is still very difficult for humans because it has a thin atmosphere, very cold temperatures, and high radiation exposure. These conditions would require advanced life-support systems. |
